I've only choose two videos on youtube because of the credibility of the speakers, but if you have something to share, be free and we debate!

...substantial species extinction, large risks to global and regional food security, and the combination of high temperature and humidity compromising normal human activities..."
Yeah well going much further into the debate I'd have to start studying the subject thoroughly. But I know that there's debate about global warming in science community
you can figure out a theory to explain it but as far as I know that theory is yet to comeThat theory is evolution...
And I suppose even if you had one you'd have to validate it one way or another.Again, seeing something happen directly in real time is not the only thing counted as evidence.
...there's no empirical evidence of it.http://www.talkorigins.org/faqs/comdesc/
there's relatively small but fundamental assumptions and simplifications done based on nothing but 'else it doesn't work'.Name them.
Google is very far from sufficient when examining this so by any means if interested...Google is a search engine, it is quite sufficient for finding references and published papers on evolution which is what I used it for.
... read!I gave you an extensive list of research on the topic, what am I supposed to read? What's the problem exactly with what I linked? Do only your non-peer reviewed books count?
I can recommend you some books.Gee, thanks. Go on then, what are your recommendations?
I'm not religious enough to believe bacteria turns into human if you're patient - and just because they taught you so.So are you religious or not?
The existing ones develop but new ones don't pop out.Of course they don't pop out, if they did we'd call it the revolution of species or something like that. They evolve slowly over millions of years and go through a myriad of life forms to go from bacteria to human.
Favorable mutations yeah, I'm not sure, theoretically it even might be possible, but if you've studied math... :PIf you've studied math... what? What does math say about favourable mutations?
You can't just throw everything at my face and say 'reply'I'm arguing your point about there being no evidence for macro evolution. You can choose not to read it, but then it would be dishonest of you to claim there is no evidence.
lots to debate about evolution on a scientific basis and by legitimate scientists.But you haven't shown that at all. Fringe books by members of a blatantly religious group don't count as legitimate scientific debate.
So wtf do economic interests have to do with science?
it happens every day, every season.I have to correct this :) The climate is defined as long term (around 30 year) variations in weather patterns, so no the climate does not change every season.
i am not concerned about climate change, for a few reasons:Individually, yes. But if everyone isn't "that concerned about climate change" we're sunk
1. it is an issue that is far beyond my control
2. i have a basic faith that humanity possesses the efficacy to adapt to threatening circumstances, should man's impact on climate really be so great
I think you're being naive and extremely optimistic. Look at this picture, which shows temperature relative to current against time. It has been around 3degC warmer in the past. Note that timespan it took - say 10,000 years. We're currently warming at nearly 1degC/century - that's 100degC in the same timespan. We're moving into uncharted territories, and there isn't really a brake - imagine removing the amount of GHGs from the atmosphere that humans have added in the past 2 centuries. I think we need to be worried about that! Evolution cannot operate over such a short period of time.
3. climate has changed dramatically over earth's history, creating new benefits and detriments for life, and these benefits and detriments are what help to drive selection of biological evolution
...necessary element in the data data determining climatehehe, pedantic but ultimately true
significance to the conversation of this graphThe significance is the rapidity with which Earth's atmosphere is warming and how this means humanity needs to "adapt to threatening circumstances" sooner, rather than later. In my opinion, that should be asap.
the temperature is relatively lower now as compared to those assumed from observations of historical evidenceYes, that is what the graph shows. The top two are estimates of historical temperature based on two different ice cores. iirc they measure the relative presence of oxygen-12 and oxygen-16 or something. The fact they agree suggests it's quite accurate.
i don't understand what this means.In the near future, the Earth's atmosphere will probably become hotter than it has been for a long time :p As a result, we have no primary data of the effects - we can only estimate by extrapolating.

Evolution cannot operate over such a short period of time.You were suggesting that climate change is a driving force of evolution (I agree). My point is that evolution happens on a very slow timescale; it won't be able to respond to the rapidity of the forecast climate change.
i don't know how this relates to the discussion.
worrying about something doesn't solve it. being concerned about an issue doesn't preclude being aware of, attentive to, or active in its resolution.True. But I would hope you would "make a stand" or at least have made your mind up before "the oceans swallow half of the planet" and you "watch the water boiling from the gel of [your] children's eyeballs"
does it seem that's what i would do?Sorry, I wanted to add that note in for anyone reading. Better to close the argument before it starts :)
is there some reason why an unfavorable speculative consequence to the assumed significance of humanity's impact on earth's climate (such as catastrophe) should be valued over a favorable (can you conceive of a favorable outcome)?I commend your complexity of communication. YES there is one very big reason that we should focus on the negatives, and you alluded to it...there are more and they are far more significant! I can't think of a bonus either, really. Apart from some places getting sunnier, but that's trivial really.
you should understand that i was joking when i said that.Sorry, I didn't recognise it. That puts my heart at rest :)[/q]
2. sources, pleaseYou must listen to the stars with your heart and the truth will be revealed.
It is extremely likely (95-100%) that human influence has been the dominant cause of the observed warming since the mid-20th century
If the belief in global warming is based on scientific predictions which is based on empirical evidence, how is it then a 'blind' belief?
"Then why there isnt a corresponding increase in temperature?"
"Correlation doesnt means causation."
"Again, co2 isnt the main enemy, methane is much worse as a greenhouse gas."
When you move rocks that weighs like 20 ton, 35 ton, it doesnt matter how many people you have to move those rocks, the point is the technique. Also note that in Inca there is these "zigzags" rocks over there in which matchs with other megalithic strucutres in the world that these people DIDNT HAVE CONTACT between each other. See some people make igloos, others tents and so on. Why would these extraordinary people make pyramids? all around? …think about it, it must have a logic in it.
we still do not have complete certainty about if the current climate change was only, mostly or partially ... caused by [humans]

But remember: Einstein came up with his theory without "proper math(or the math that the most of the people used to tackle with this subjects at that time), now we call it by Quantum Gravity(quantum theory)The hell does this mean? Quantum mechanics didn't exist when he worked on SR/GR...
The point of that comment was to tell you that CO2 is not a poison but a basic element of lifeSomething can be both poisonous and a "basic element of life"...
even if its presence increased by 1000% from the current level the worst effect I could think off is it would cause light headiness.How do you know that? What are you qualifications?
